: In recent years, a new class of composite materials, polymer nano-composites, has been developed due to progresses accomplished in the field of nano-materials offering an interface in the field of nano-technology and polymers. The consumption of nano-composites is growing rapidly on a global basis due to unique mechanical and physical properties, electrical conductivity, thermal stability and low density, and, thus, so much attention has been paid to nano-composites in the fields of military, electronics, medicine, aerospace, etc. Nonetheless, the cost of manufacturing, equipment to fabricate samples and eventually nano-composites with required final characteristics could be effortlessly named only as a few examples of the challenges in this field to be addressed by universities and Research Development centers. On the other hand, there exist other underlying aspects such as the orientation of nano-particles in the polymer phase, interphase layer formation, the degree of nano-particles dispersion, distribution quality in the polymer phase, the degree of crystallinity in the semi-crystalline polymers, etc. The said factors significantly affect the final properties of the nano-composites. Such variable however can be controlled by means of the methods used for the fabrication of nano-composites. With regard to the latter influence, today, low-cost fabrication methods, without the use of chemical compounds, are of a vital requirement. In this project, the investigation, feasibility, design and fabrication of the second phase of a micro-extruder-micro-injection device, being a part a comprehensive project on the manufacture of a micro-compounding instrument, are presented. To fulfil this goal, design and reverse engineering approaches were used for the design and manufacture of the micro-injection molding unit utilizing the design requirements obtained through the collected information. The fabricated unit includes pneumatic system, conical mold, conical mold case, transfer cylinder, transfer cylinder holder, thermal system of the mold, thermal system of the transfer cylinder and the control of pneumatic system and control of thermal system. It is noteworthy to mention that the machine not only is able to be employed for the fabrication of nano- composite it can be also utilized in other industries such as pharmaceutical and food processing. The research falls in the overlapped areas of the classic science including mechanical engineering, polymer science and chemistry aiming at developing advanced sciences and technologies with a close look to nanotechnology acknowledging its significant role in sustainable development nanocomposites.
